I did an experiment this year. Most of my tomatoes are out in the full sun and two heirlooms are in partial shade. The latter two are doing much better than the rest. I live in zone 6B, Ohio.
We have had the same experience with a variety of plants. I heard several months ago that the sun’s rays would be more intense so we planted in the sun and under partial shade. Broccoli, tomato and pepper plants did fine under shade but we lost about 45 plants that were in full sun. I’m in zone 5 New Hampshire.
My tomatoes are in a lean-to greenhouse and they get dense shade from 3 pm on. But at 6000 ft elevation in Montana (zone 3) the sun is very intense and the days are long. I had read that they don’t need as much light as say, a cucumber, so they’re against the wall and doing great.
Good observation! Totally makes sense. Tomato roots do not like excessive and/or prolonged heat. Some varieties do better than others. For example, heirloom Mexican varieties handle the heat better than northern varieties. That has been my experience. The partial shade is a fantastic way to combat that. Another way is to keep root zone temperature lower. Two tricks I use to achieve that is a thick mulch layer and splitting the watering schedule up so during peak temperatures the roots get low doses of water to “cool off.” If I had the partial shade option at my current spot I’d use that though to help conserve water. Lucky you! 😃. If you haven’t checked out some Mexican heirloom varieties I recommend trying. The leaf size and shape of the “Zapotec” variety I grow is wild. It’s so cool! The leaves are huge compared to other varieties I’ve grown. And a different shape. Happy gardening. Cool to see gardeners here sharing what they’ve experienced. Peace and love from Traverse City Michigan. ❤
Excellent demonstration of using the process of differential diagnosis well-known to us physicians for the diagnosis of plant disease from symptoms exhibited by the plant. Bravo!
This is a great explanatory video. Another variable that can cause leaf curl and deformity - is herbicide drift (not herbicide contaminated soil). I say this because in my area it is a concern - my city has ordinances for weed control. I have neighbors that occasionally spray for weeds in their yards. Occasionally, that spray makes its way into my garden. It does not impact every plant, nor the entire plant - so it can be really hard to diagnose.
Always perfect timing with your videos.. Out of 62 tomatoes I have 5 have that are curling.. I've been putting them off but after seeing this video I am going to get a move on it and fix them 😆
I have not e perienced leaf curl until this year. Amis Paste tomato (MIG seed). Only one out of 3 Amish Paste plants and out of all 20+ tomatoes in general. I do believe tbe extremely hot dry weather got to it. Glad to know it is not a gonner, it just looks sad. Thank you Luke for this timely video as, it seems that a lot of us are experiencing this for this season.
Thanks for this info. I have on San Marzanothat has leaf curl just at top half of plant. Been getting lots of rain in Wisconsin. Will check plant closer tomorrow.
Hi Luke, I'd appreciate your opinion on a tomato plant. I am a container gardener, Tomatoes are all in 5 gal plastic pails (Homer buckets). All are fertilized and watered the same. I do aspirin solution spraying every 2 weeks. I had a Centiflor pop up in a bucket that I had grown Centiflor in last year. I had an extra pail so I planted it. Overall I'd say the plant is quite healthy. Loaded with toms and blossoms. I have leaf curl on some branches. The curl is downwards (concave) -- on mid to upper branches. The branches with curled leaves have no other abnormalities. Other branches are totally normal. The plant has no insects and no sign of any other disease like early blight. I'm not sure if this is normal for a Centiflor. Regards, David
This explains a problem i had several years ago. I had a wonderful garden year, and then the following year, i added a couple of raised beds and then filled all my beds with some compost made at a local town transfer station. Everything came up and then stopped growing - severely stunted plants. I was so discouraged that i didn't plant again for 2 or 3 years. Then, i tilled all the beds, added new compost and Trifecta and I've had great gardens again. I'm sure there was some sort of herbicide in that compost from the town.
Hi Luke. Thanks for the great information. Would you consider writing a box on good and bad insects in the garden. I am a new gardener and knowing good and bad bugs is so important in gardening.
P.S. I googled and read that white fly and silver winged white fly can also carry the leaf curl virus, as well as the leaf hoppers you already mentioned.
Perfect timing on this video, it's like you were next to me when I was in the garden today lol 😂 my tomato leaves are curling and i was wondering the cause and this makes so much sense! we are having crazy weather in southeast Wisconsin this spring and summer...so many tornados and severe storms!
I got 33 tomato plants atm (greetings from the wet... and not sunny, extreme bad spring and summer ... Netherlands) .. 1 i have in the front yard also has leave curl, but the lower leaves do NOT have leave curl (the 3 next to it havent got it, they are less exposed to the wind) ... its on the most windy part of my entire garden .... so thank you for this vid... because i have been wondering what it could be
This information will explain my tomato plant problem! We try to do everything right but still get very poor results.Would trying a few plants in pots with new soil next year help?
romas are typically a bit more heat resistant than other tomato plants but are they all up against glass? I work in a massive south facing greenhouse and the ones up against glass will naturally curl over time when they get too much sun, its a part of their evolutionary safety measure so try not to worry about it to much and move the plants away from the glass a tiny bit. Tomato plants originate from south america under a canopy of trees so leaf curling can simply be a defensive mechanic to reduce to much sun.
My tomatoes are troopers. Strong winds and heat and dry spell and they are still growing flowers. We also have a groundhog who likes to dig right next to them. Stay Calm and Tomato On 🤣
I didn't know the leaves couldn't uncurl! I guess that would explain why I'd try to treat my plants and wouldn't see any difference the following days 😂
Luke, have you given up growing tomatoes staked on a single stem process? I see that you’re just letting them bush out. Have you grown into a preference? Thanks for all the info on leaf curl. That really helps.
Curious, what are the little boxes on the outside of your raised beds at the 3:00 mark? Remediation of soil doesn't necessarily mean removal of soil. It can be done with time or even with fungus that will consume and remove toxins.
Certain cover crops will remove herbicides from the soil, like grasses. Also, a lot of the hysteria over herbicides is a little extreme. Not that you want them near your tomatoes, but a lot of things out there are only active for a short period of time, including the dreaded glyphosate (lay people mistakenly always call it roundup, which is a brand, not an herbicide). Graze on can be a concern in more rural areas and you should do your due diligence.
When is it too hot for tomatoes? I'm in 6B zone and this heat and humidity is insane. I don't have leaf curl, but it seems to me that I don't have as many flowers on the cherry tomatoes than I usually have. Should I consider a shade cloth?
Compost too hot causes it too. Put 21 tons of compost in a big pile and it heated back up. All those plants twisted and curled for a few weeks. Checked soil temps, way too hot. But the plants in pots were just fine. Same compost mix. I increased watering, hit em with some N, and a few weeks later, 80% of them are back to normal. The other 20% still not happy.
My romas are doing just fine in my open raised bed, but my other varieties are suffering. I only added bone meal around the base of the plant and covered that with chemical free grass clippings. Not sure if the extremely wet summer could be the problem. No bugs have been seen. No new soil or compost was added. Any ideas or solutions?
My California Wonder peppers have overturned leaves with purpling. No other pepper plants are doing this in a bed with many varieties. What's with that?
Something else to consider is bacterial wilt. I have two Orange Icicle plants with it. I picked up the seeds at the swap this spring. I'm wondering if anyone else is having this issue with their Orange Icicle. The seeds were not MIgardener seeds.
Isnt glyphosate the most common herbicide? It seems to be one of the most concerning, at the very least. Its been known to be a carcinogen since the 1980's, yet is still used on a regular basis. For those that dont know, glyphosate is one of the main ingredients in round-up.
Roundup is bad but it is nothing compared to Grazon. Roundup breaks down chemically in a week or so. Grazon lasts for 25 years in some cases. It even survives animal digestion and persists in the manure. I hate eco fearmongering but I honestly believe that Grazon can destroy the world ecosystem if it isn't outlawed. The Grazon will eventually contaminate all the soil on earth if it isn't stopped. And who knows what it is doing to our bodies. It is in all the meat, dairy, and grains. Anything that is botanically grass isn't killed by Grazon and is accumulated in the plant material and any animal that eats it.
Glyphosate is the active ingredient in Roundup, but it's not the main ingredient by volume. Roundup is mostly water. The patent on glyphosate is long expired, and is sold in generic formulations by dozens of manufacturers and brands. Not even the EU regulators list it as carcinogenic. The IARC finding that it is a "probable carcinogen" stands alone among all other global health agencies, and is not well supported by the published data. Even then, IARC only found a possibly increased risk of certain cancers, and not overall increased cancer prevalence. Glyphosate has been shown not to increase cancer prevalence in rats and rabbits on a lifelong feeding regimen. Now, Roundup as a commercial product does contain some nasty stuff. Polyethoxylated tallow amine (POEA) was used as a surfactant until 2011, and is judged to be significantly more toxic than glyphosate. Most generic formulations do not contain this surfactant.
Have 10 indeterminant tomato plants in one of my raised beds and there are 5 varieties. 8 plants are very healthy and just one variety has what looks like leaf curl. Now I'll be trying to figure out which of those factors you mentioned is affecting it. The affected variety is a dark colored variety of tomato, sorry the name escapes me at the moment.
Most of my tomatoes are planted in the ground, and slightly protected from wind. But I have 2 in a raised bed that are curled, and get full sun and full western wind. This is farm country with lots of wind, and the sun has been incredible! I believe it to be from that, and not farm chemicals. Both plants have set fruit (San Marzano tomatoes).
My tomatoes were doing wonderful and then we went hot really fast. All of my tomatoes are completely curled. Unfortunately we have not had any relief from our heat. I am in zone 9 Florida. Then my sting beans and corn were attacked by fire ants. I have never had this before and they have killed all of my plants. This is my worst season so far.
They fall over for me sometimes from heavy overhead watering (the water weighs them down), physically being pushed, or if they are huge and have bloomed and the weight of them just gets to be too much. Usually harvest is coming soon if a bunch of them are falling and yellowing.
I want to put 40% shade cover over mine but some are in raised beds and others in fabric grow bags so not sure how I’m going to accomplish this. But I do have curl in some of my plants.
@@gferraro8353 thank you for the suggestion. My tomatoes are all indeterminate and will probably grow to a height of 8’ or more. I don’t know how I’d accomplish it with umbrellas. I might just have to let them be and see how it shakes out.

Just kind of looks like it needs water?
Sort of like many trees around my area; they look like they cannot uptake enough water or nutrients to live.
So if mine curl every day in direct sun...but then unfurl every night when it's cooling off... how?
Plants are living organisms able to respond to changes in their environment.
Never heard of a leafhopper here in North Idaho.
tree leaves will do the same.
Too much sun.
